chore(gs/xanthous): fix for hgeometry 0.12.0.1

The breaking removal of triangulationEdges was not that big of a deal
after all: It was just renamed to edgesAsPoints apparently, so the fix
is easy enough and we can save one override.

hgeometry-combinatorial's doctests seem to trigger some kind of GHC
dynamic linking bug (https://github.com/noinia/hgeometry/issues/132) so
we disable the tests.
